json解析

用 map[string]string，切片解析json陣列

    package main
    import (
        "encoding/json"
        "fmt"
    )
    type Transport struct {
        Time  string
        MAC   string
        Id    string
        Rssid string
    }
    func main() {
        var st []Transport
        t1 := Transport{Time: "22"
 
, MAC: "33", Id: "44", Rssid: "55"}
        st = append(st, t1)
        t2 := Transport{Time: "66", MAC: "77", Id: "88", Rssid: "99"}
        st = append(st, t2)
        buf, _ := json.Marshal(st)
        fmt.Println(string(buf))

        var str = string(buf)
        var st1 []Transport
        err := json.Unmarshal([]byte
 
(str), &st1)
        if err != nil {
            fmt.Println("some error")
        }
        fmt.Println(st1)
        fmt.Println(st1[0].Time)

        var Msg []map[string]string
        json.Unmarshal([]byte(str), &Msg)
        fmt.Println(Msg)
        }
